To all whom it may concern.

Be it known that 1, JOHN S. RAPSON, a citizen of the United States, andresident of the city of Jenkintown, county of Montgomery, and State ofPennsylvania, have invented "an Improvement in Combination Desk 1mlements, of which the following is a speci "ca tion.

My invention has reference to combination desk implements, and. consistsof certain im rovements which are fully set forth in the fol owingspecification and shown in the accompanying drawings, which form a partthereof.

The object of my invention is to provide an article'for use on writingdesks which may be employed for numerous purposes in connection withpaper, such as opening letters, holding the sheet of paper steady duringerasure therefrom, ruling straight or curved lines, drawing angles ordescribing circles of various radii and measuring distancesl Myinvention consists of an article of manufacture consisting of a flatplate rectangular in general outline provided with a central opening anda prong at one end; further in having the end of the prong provided witha small hole and the edges of the plate in alinemerit therewith formedwith notches at scaled distances a art.

A My invention a so com' reliends minor details of construction whictogether with the features above specified, will be better understood byreference to the drawings, in which: i

, Figure 1 is a perspective view of the combination desk implementembodying my invention; Fig. 2 is a plan view of the same; and Fig. 3 isa sectional view of the same.

The article is stamped from flat sheet metal; being of an integral pieceand having the following features of construction.

A is the body of the plate and is essentially rectangular and providedat one end with a prong or fixed jaw I, forming a slotted portion iterminating in a knife-edge J and constituting as a whole an envelop o)ener. The central art of the plate is provide with an openingpreferably rectangular, so that when the plate is pressed down upon thesheet of paper the latter may be held in clamped position while exposinga confined portion'from which an erasure is to be made.

This erasure may be thus performed without the crumpling of the sheet ofpaper.

The plate is made rectangular on the outthe scale marks, and these maybe for every side upon three of its sides and preferably on theboundaries of the aperture B so as to provide straight edges and rightangles for drawing upon paper. The nose of the jaw or prong I isprovided with a small aperture N -in substantial alinement with one edgeL- which may have a scale K. This ed e L may also be provided withnotches O in ine with quarter of an inch, or otherwise, as desired.

By inserting a pin through the aperture N and using it as a center, thelate A may-be rotated about said pin, and by placing a pencil point inany one of the notches'O and applying pressure laterally to the saidpenc1 the plate may be rotated about the pin for describing circles orcurved lines of any desired radii within the range of the scale K.

This scale may be used for drawing or any other purpose wheremeasurement is required. The curvedportions of the jaw or rong I mayalso be used for drawing curved ines. The plate as a whole. may beemployed as an ed e for holding a stub or other paper while thedooseportion is being torn or severed for detachment.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. As an article of manufacture a desk implement consisting of a thinflat plate A of stamped sheet metal and uniform thickness provided withan aperture B in its body and a fixed jaw I at one end forming a slottedportion t to constitute a letter opener;

2. As an article of manufacture a desk implement consisting of a thinflat plate A of stamped sheet metal and uniform thickness provided withan aperture 13 in its body and a fixed l at one end forming a slottedportion i terminating in a knife edge asat J to constitute a letteropener the bevel of which knife edge is wholly on one side of the plate.

3., As an article of manufacture a desk implement consisting of a fiatplate provided with an aperture through which-to expose a clampedportion of a paper sheet and a bounding edge having notches at equaldistances'apart and saidlate also having an aperture in line with t enotched edge for the insertionpf a pin when using the notched edge as acompass.

4. As an article of manufacture a desk im lement consisting of a flatplate having a Xed jaw at one end to form an envelop (ipener seidjawhaving near its end an aprstraight edge in line with the aperture and 10,fiure end the body of the plate having 8.- provided with a scale andnotches in its edge ,Js'traiglrt edge'in line with the aperture and atequal intervels'elong the scale. provided with a scale. In testimony ofwhich, invention, I have 5. As an; article of manufacture a deskhereunto set my hand. imgvlement consisting of. a flat plate having JOHNS.
